Hosea is the first book of the twelve minor prophets. Because the times are outwardly prosperous, idolatry prevails and immorality is rampant. Hosea urges a return to God in order that He may show mercy and forgiveness.

Hosea 7

7:6 For they have made ready their heart like an oven, whiles they lie in wait: their baker sleepeth all the night; in the morning it burneth as a flaming fire.
